Types

type Conn

type Conn interface {
	// SyscallConn returns a raw network connection.
	SyscallConn() (RawConn, error)
}

Conn is implemented by some types in the net and os packages to provide access to the underlying file descriptor or handle.

type Errno

type Errno uintptr

An Errno is an unsigned number describing an error condition. It implements the error interface. The zero Errno is by convention a non-error, so code to convert from Errno to error should use:

err = nil
if errno != 0 {
        err = errno
}

const (
	EPERM       Errno = 0x1
	ENOENT      Errno = 0x2
	EACCES      Errno = 0xd
	EEXIST      Errno = 0x11
	EINTR       Errno = 0x4
	ENOTDIR     Errno = 0x14
	EINVAL      Errno = 0x16
	EMFILE      Errno = 0x18
	EAGAIN      Errno = 0x23
	ETIMEDOUT   Errno = 0x3c
	ENOSYS      Errno = 0x4e
	EWOULDBLOCK Errno = EAGAIN
)

func (Errno) Error

func (e Errno) Error() string

func (Errno) Is

func (e Errno) Is(target error) bool

func (Errno) Temporary

func (e Errno) Temporary() bool

func (Errno) Timeout

func (e Errno) Timeout() bool

type RawConn

type RawConn interface {
	// Control invokes f on the underlying connection's file
	// descriptor or handle.
	// The file descriptor fd is guaranteed to remain valid while
	// f executes but not after f returns.
	Control(f func(fd uintptr)) error

	// Read invokes f on the underlying connection's file
	// descriptor or handle; f is expected to try to read from the
	// file descriptor.
	// If f returns true, Read returns. Otherwise Read blocks
	// waiting for the connection to be ready for reading and
	// tries again repeatedly.
	// The file descriptor is guaranteed to remain valid while f
	// executes but not after f returns.
	Read(f func(fd uintptr) (done bool)) error

	// Write is like Read but for writing.
	Write(f func(fd uintptr) (done bool)) error
}

A RawConn is a raw network connection.

type Signal

type Signal int

const (
	SIGCHLD Signal = 0x14
	SIGINT  Signal = 0x2
	SIGKILL Signal = 0x9
	SIGTRAP Signal = 0x5
	SIGQUIT Signal = 0x3
	SIGTERM Signal = 0xf
)
